Weapon Skills

Each Weapon has a skill set to it. By default you can use a weapon skill twice per long rest. Upgrades exist to increase the amount of uses or change the reset condition to short instead of long rest. Characters can use the Character Builder to learn new skills. When applicable to the weapon you have equipped, you can use this Weapon Skill you learned as well as the default skill. You must be proficient with the weapon type you're wielding to use the weapon skill. Wands have no weapon skill and cannot be used with learned weapon skills.

If a Weapon Skill refers to your Skill Die, this die is 1d8 by default.

Saving Throws. Some of your Weapon Skills require your target to make a saving throw to resist the Skills' effects. The saving throw DC is calculated as follows:
Maneuver save DC = 8 + your proficiency bonus + your Strength or Dexterity modifier (your choice)
Some character abilities allow you to change your modifier for (certain) weapon skills.
